Walker 242-1359 Ignition Knock (Detonation) Sensor

OE Knock Sensor for Land Rover LR2

Walker 242-1359 is an OE replacement ignition knock sensor built to monitor engine vibration and detect detonation events. It is engineered for direct fitment on 2008-2012 Land Rover LR2 applications with a factory-style electrical connection and sensor-only design.

Key Features

• OE replacement ignition knock (detonation) sensor
• Engineered for the resonant frequency and sensitivity required by the application
• Spade terminal type with 1 rectangle connector
• Female connector with 2 male terminals
• Heat- and oil-resistant construction for engine-block and cylinder-head environments
• Direct replacement for factory threaded mounting locations

Product Details

The Walker Sensor Only line focuses on direct-fit replacement sensors that match original electrical and mounting requirements. Part number 242-1359 is tuned to detect knock at the frequency expected by the engine control system, allowing the ECU to adjust ignition timing when detonation is present. On 2008-2012 Land Rover LR2 models, this helps maintain proper spark control and stable engine operation. Walker 242-1359 is built for OE-style output and factory-style connection points, making it a practical replacement when the original sensor has failed or set a diagnostic trouble code.

This part cross-references no listed aftermarket part numbers for the same application.

Common Issues This Part May Address

• Knock sensor fault codes such as P0325 or P0330
• Audible spark knock or detonation under load
• Incorrect ignition timing response from the ECU
• Reduced fuel economy caused by timing being pulled back
• Drivability concerns related to failed knock detection

Installation Notes and Tips

Verify the connector style, terminal layout, and threaded mounting location before installation. Clean the mounting surface and inspect the harness connector for corrosion or damage before connecting the new sensor. Because this is a sensor-only replacement, reuse the vehicle’s existing mounting provisions and follow the factory service procedure for torque and connector routing.

Quality Assurance

Walker knock sensors are built to OE specifications for frequency range, sensitivity, and electrical output, with materials selected to withstand heat and oil exposure in the engine bay. Part number 242-1359 is a direct replacement for 2008-2012 Land Rover LR2 knock sensor applications.
